CHECK-ROW'ER FOR CORN-PLANTERS.

SPECIFICATION forming part of Lettqrs Patent No. 367,964, dated August 9, 1887.

Application filed May 26, 1857. Serial No. 239,485. (No model.)

To all whom it may cor Learn..-

Be it known that I, ALVIN DEVINE, of Bantoul, in the county of Ohampaign and State of Illinois, have invented a new and Improved Check-Bower for Oorn-Planters, of which the following is a full, clear, and exact description. I

My invention relates to an improvement in check-rowers for corn-planters, and has for its. object to provide a planter that is operated from a wire or rope stretched at the side, wherein the wire need not be detached at the ends when the planter is reversed, and also wherein the operating mechanism will be strong andsimple and not liable to lose motion by slight wear.

The invention consists in the construction and combination of the several -parts, as will be hereinafter fully setforth, and pointed out in the claims.

Reference is to be had to the accompanying drawings,'forming a partof this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the planter. Fig. 2 is an end view thereof. Fig. 3 is a side view of the planter. section through the machine. Fig. 5 is a detail plan view of the drop-arm, and Fig. 6 is a section on line a w of Fig. 4.

In carrying out the invention the frame 1 is provided with the ordinary runners, 2, seedboxes 3, and the ordinary sliding drop-bar, .4, whereby the fiow of seed is regulated from the boxes. 1

To the inner forward ends of the seed-boxes, near the top, outwardly-extending angle-irons 5 are secured, adapted to support a transverse bar, 6, centrally which bar, upon the rear edge,- a downwardly-projecting tubular bracket, 7, is secured. To the upper side of the bracket 7 aflanged tube, 8, is vertically attached, the aperture in said tube aligning the aperture in the bracket. 7

A. rod, 9, provided with an elongated slotted head, 10, is'loosely entered the apertures of the flanged tube 8 and bracket 7, the head of said rod having a bearing upon the flange of the tube 8.

The lower end of the rod 9 is made to project below the bracket 7,and is attached at Fig. 4 is a transverse vertical ing drop-bar 4 to the left of the center, the said drop-bar being adapted to receive a reciproeating motion through the medium of the rod 9. At equal distances each side the bracket 7 one end of a segmental bar, 14, is secured to the upper face of the transverse bar 6, which segmental bar is adapted to extend to the rear of the machine, and is provided with horizontal parallel end portions, 15, as shown in Fig. 1.

An arm, 16, is pivotal-1y attached to the bracketbeneath the flange of the tube 8 by .means of straps 17, secured within the slotted inner end of said arm, the said straps being adapted to turn loosely upon the bracket.

The arm 16 is adapted to extend normally longitudinally the planter and project a distance beyond one box, 3, and is provided at its outer end with a fixed bar, 18, at right angles to the arm, proj ecting outward an equal distance upon each side.

The outer ends of the fixed bar 18 are slotted, and within said slots agrooved pulley, 19, is pivoted, and above said pulley a U-shaped guard, 20, is provided, attached to the slotted ends of the bar 18 by the same pivotal bolt carrying the pulleys.

Near the outer ends of thearm 16, upon the under surface, a spring-plate, 21, is made to project upon each side, which plate, engaging the under side of an upwardly-extending an gular stop, 22, attached to the outer and forward side of the seed-boxes, as illustrated in Figs. 1 and 2, serves to limit the outward throw of the said pivoted arm. In the upper edge of the inner arm of the angle-irons a slot is cut, adapted to receive the weighted end of a latch, 23, pivoted beneath thearm 16, the said latch being disengaged by the driver through the medium of a rope or cord, 24, attached to the inner end of the latch, as shown in Fig. 2.

Upon the upper outer end of the arm 16 a lever, 25, is pivoted,'having a notched inner end and a metal loop, 26, formed upon the outer end, projecting across and beyond the fixed bar 18. A spring, 27, also attached to the upper surface of the arm 16, is made to engage the notched end of the lever 25, adapted to retain the same normally parallel with the arm.

About centrally the upper surface of the lever 25 a connecting-bar, 28, is pivoted, which bar, extending inward, is made to slide in ways 29, formed upon the arm 16, and a second short connecting-bar, 30, having a downwardly-bent inner end, is pivoted at its outer end to the long connecting-bar 28, to operate in unison therewith. The bent inner end of the short bar 30 is adapted to enter the elongated slot in the head of the rod 9.

At each side of the ways 29, upon the arm 16, the rightangular arms of a U shaped supporting-rod, 31, are pivotally secured, the inner closed end of which rod 31 is provided with two or more depressions to receive the short connectingbar 30 and lift the same from engagement with the rod 9 when the bent inner end of 'thc supporting-rod is brought in contact with the bar 14 as shown in Fig. 4.

In the operation of the planter a rope, 32, is stretched from one of a field to the other, provided at intervals with a series of balls, 33, the said rope and balls being adapted to pass through the loop 26 of the lever and over the pulleys upon the fixed arm. As the planter is driven along, the balls, engaging the reduced ends of the loop 26, carry the lever 25 outward, as shown in Fig. 5, thereby causing the connecting rods 28 and 30 to slide forward, which, acting upon the rod 9 to turn the same, causes the drop-bar et to reciprocate in one direction, the said bar being almost imme diately reciprocatcd in an opposite direction by the return of the aforesaid operating parts to their normal position. This opposite movement is produced by the balls 33, passing through the large end of the loop 26, whereupon the lever 25 is returned toits normal po sition by the spring 27. \Vhen it is desired to reverse the planter and sew another row,the cord 2t is pulled and the latch 23 lifted. The planter is thentnrnei'l, which movement causes the arm to travel in the direction of the opposite seed-box. The supporti ng-bar 3]. then coming in contact with the guide-bar 14, raises the short connecting-bar 30 out of engagement with the operative mechanism of the dropbar. Thus the position of said bar is not changed when reversing. \Vhen, however, the arm 16 is locked over the opposite box, the connecting-bar 30 is made to rc-engage the rod 9, and, the machine being driven forward, the planting is continued.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with aplanter, aslotted rod journalcd between the boxes, the dropbar reciprocating in said boxes, and a pivoted connection between said rod and drop-bar, of a swinging pivoted arm adapted to extend over and beyond the boxes, a spring-actuated lever pivoted upon said arm and having an elongated loop attached at the outer end, a pivotal dual rod-connection between said lever and slotted pin, a trip-bar pivoted to said arm beneath one connecting-bar engaging the aforesaid pin, a ball-carrying rope fast at each end adapted to be engaged by said loop, and means for operating the drop-bar from said pivoted arms when extended over the seedboxes, substantially as shown and described.

2. The combination, with a planter, aslotted rod journaled between the boxes, the dropbar reciprocating in said boxes, and a pivoted connection between said pin and drop-bar, of the swinging pivoted arm 16, the spring-actuated lever 25, pivoted on said arm, provided with an elongated loop, 26, the pivotally-conneeted and sliding conneeting-bars 2S and 30, the fixed bar 18, attached at right angles to said arm, pulleys 1f), pivoted in slots on said bar, and a ball-carrying rope passing through said pulleys and loop, substantially as shown and described.

3. The combination, with a planter, a slotted rod journaled between the boxes, the drop bar reciprocating in said boxes, a pivoted connection between said drop-bar and rod, and a rearwardly-extending U-shaped guidebar,14, attached at each side of said pin, of the swinging pivoted arm 16, the spring-actuatedlevcr 25, provided with an elongated loop, 26, the pivotally-connected and sliding conncctiug-bars 2S and 30, a right-angular bar, 31, pivoted to said arm beneath the connecting-bar 30, adapted to engage said guide, the fixed bar 18, carrying-pulleys 1!), and a ballearrying rope, 32, passing over said pulleys and through said loop, and means for releasing and swinging said arm to the rear, substantially as herein set forth.
